RADIATOR FOR MOTOR-DRIVEN VEHICLES.

Application filed March 18, 1921. Serial No. 453,281. I

To all whom it may concern:

Be it known that I, HARRY It. SONGER, a citizen of the United States, and resident of WVichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Radiators for Motor-Driven Vehicles, of which the following is a specification.

My invention relates to improvements in radiators for motor driven vehicles. The

object is to increase the cooling effect upon the motor, especially when the car is in motion.

In accordance with my invention, I cause a number of streams of air to pass first through the lowest portion of the radiator, thence upward to impinge on the bottom of the water-chamber at the top of the radiator, or to pass through said chamber, thence being deflected upon the motor. The temperature of these air streams being lower than that of the'water at the top of the radiator, the moving air will absorb heat from the water in the cooling system.

An auxiliary cooling effect is produced by a novel construction of the cap of the radiator filling tube, wherein the cap is open to atmosphere through lateral and vertical orifices, whereby the escape of steam to atmosphere, and the circulation of cool air through the filling tube, are effected. The escape of water through the same channel is obviated by a self-closing valve.

The above improvements are illustrated in the accompanying two sheets of drawings, in which- Fig. 1 is a side elevation of a cooling system constructed according to the invention, showing the adjacent portion of an internal-combustion motor; Fig. 2 is a rear elevation of a radiator and the improvement, showing a modified arrangement of the airflues omitting the deflector; Fig. 3 is a detail plan view on section line III of Fig. 2; Fig. 4 is a vertical section of the lower portion of the radiator and a communicating air-chamber; Fig. 5 is a partly sectional side view of the water-chamber and associated parts; Fig. 6 is a vertical section of my improved filler-cap, and Fig, 7 is a plan view of the float valve detached.

On Figs. 1 and 2, A indicates a radiator of well known construction, and B, the usua1 watenchamber at the top thereof. To

the inner face of the lowest part of the rad ator, I attach a sheet metal chamber 1, having upper and lower flanges 2, 3, by

which the chamber is secured to the radia-.

tor. In the case of the Ford radiator, which is the make illustrated, the upper flange 2 is secured to the steel bar 4. The top of said chamber is perforated to receive the lower ends of a series of air-tubes 5 01* 6, which extend upward to a level close to, or above, the bottom of the waterchamber extension 7.

It is to be noted that all of the air-tubes may stop short of the part 7 In that case, their upper ends will be supported by a metal bar 8,01, its equivalent, secured at 9 to the radiator, and having openings through which the tubes extend.

If it be preferred to employ all straight tubes, as 5, Fig. 1, the bottom of the extenson 7 is made imperforate.

A deflector, 10 or 12, is secured to the extension 7 for deflecting the issuing air streams down and rearwardly upon the motor, C.

Some, or even all of the air tubes or flues may be, passed through the water-chamber 7; such construction isillustrated in. Figures 2 and 5. WVith the tube formation shown in Fig. 5, the deflector 12 is fastened'to the upper portion of the extension so as to overlie the ends of the tubes. The deflector in either case is, of course, cut away or made in two parts to clear the hose connection 14:.

Fig. 2 shows the make-up of the battery of tubes when alternate tubes pass through the water-chamber; omitting, however, the larger portion of the supporting bar 8. This bar may be provided with end lugs as 9, to be secured to the radiator to prevent vertical shifting of said bar.

The operation of the apparatus described will be substantially as follows:

Supposing the car to be in forward motion, air is drawn into chamber 1 through the lower radiator section A; and by its pressure passes up through all the tubes. Issuing from the cut-off tubes 5, the air strikes the water-chamber extension 7, receiving some heat therefrom, (as the hottest water Will be at the top of the radiator) and their Water-submerged bends 6' tends to cool the water, and thence impinges on deflector 12. In connection with the alternated tubes, the form 12 of deflector must be employed-or its equivalent.

The resultant auxiliary cooling of the motor will be sufficient in my estimation to permit the removal of the usual fan. However, on Fig. 1 of the drawings I have shown a small fan, as such may be used for maintaining a draught through the hood when the motor is running and the car stationary.

Describing now the auxiliary water-cooh ing device: I form a special radiator-cap 15 with a depending inner annular flange 16 forming a dome 17, through the top of which are two or more air-ducts 18. A dome-shaped cap 19 is rotatably mounted on a bolt or pivot 20. This cap is formed with a lateral air-intake 21. A float valve 22 is vertically movable on, and guided by, pins or bolts 23 having stops 24 which support the float valve at a point below the flange 16. Thus, air blown in through intake 21 will traverse the parts 18, pass around the valve, andescape through draintube '25, to some extent cooling the air overlying the water in "the radiator. To this end .the intake 21 should be directed to the front of the radiator.

Under some circumstances water will be forced up into the tube 26, but in such cases the water will raise the float valve, which will immediately seat itseltupon the flange 16, thereby preventing the escape of any water. The passages 21 and 18 have another functionthat of permitting the continuous escape of steam or'aqueous vapor from the water, this having a tendenc-y'to lower the'te mperature of the water.

My air-tube attachment is applicable to the radiators that have no overhanging water-chamber, by attaching an overhanging water-chamber to that of the radiator.

The parts would in that case appear as shown in Fig. 1 of the drawings herein.

The rearward extension of the top waterchamber of a radiator, is a feature peculiar to the radiator of the Ford automobile. The attached constructions which I show and describe herein, were invented specially for the Ford car and are especially adapted thereto by reason of their simplicity and moderate cost of construction.

Having described my invention, I claim as new and desire to secure by Letters Patent:

In combination with a water cooling radiator, provided with a. rearward extension of its upper water chamber, an air chamber positioned at bottom of said radiator, air tubes connected to said air chamber, so as to permit the circulation 01 air through said tubes, said tubes extending upward in close proximity to the radiator, some of said tubes having curved ends passing through said water chamber extension as cooling means for said water, and said air from said tubes contacting with a deflector, causing said air to travel downward and coming in contact with the motor, alternate curved tubes being in parallel alinement with aforesaid tubes, extendingupward and adapted to discharge the flow of air through said tubes against the bottom of said water extension, as cooling means for said Water, said tubes being supported by a bar 8 mounted on brackets 9 by which means said tubes are held in proper position for the purpose of lowering the temperature of the water, an air deflector attached to the rear face of said extension and being exterior thereto, for the purpose described.
